The concept for autonomous vehicles has also been applied for commercial uses, like for autonomous or nearly autonomous trucks. As recorded in June 1995 in Popular Science Magazine, self-driving trucks were being developed for combat convoys, whereby only the lead truck would be driven by a human and the following trucks would rely on satellite, an inertial guidance system and ground-speed sensors.[1] Caterpillar Inc. made early developments in 2013 with the Robotics Institute at Carnegie Mellon University to improve efficiency and reduce cost at various mining and construction sites.[2] Companies such as Suncor Energy, a Canadian energy company, and Rio Tinto Group were among the first to replace human-operated trucks with driverless commercial trucks run by computers.[3] In April 2016, trucks from major manufacturers including Volvo and the Daimler Company completed a week of autonomous driving across Europe, organized by the Dutch, in an effort to get self-driving trucks on the road. With developments in self-driving trucks progressing, U.S. self-driving truck sales is forecast to reach 60,000 by 2035 according to a report released by IHS Inc. in June 2016.[4] They are expected to be in circulation in 5–10 years from now.[5] Uber has also joined the project with "Uber Freight"[6] which already delivers in Arizona.[7] Another big player investing in this technology is Google, through its spin-off Waymo which also delivers freights in Atlanta.[8]
